The decrease in periodic benefit costs for the three and nine months ended June 30, 2017 as compared to the corresponding period last year was primarily due to the curtailment of our U.K. plans and the de-recognition of the U.S. pension plan for participating employees who were assigned to, and worked exclusively on, a specific operating contract with the U.S. federal government. The following table presents certain information regarding the Company’s cash contributions to our pension plans for fiscal 2017 (in thousands):
